The vanilla publicity machine rolls on, as The Trivago Woman, aka Gabrielle Miller, has been 'spotted' on the tube (admittedly by Trivago itself). By all accounts she is having a nervous breakdown — as she stands in front of her own posters, leaps out at unsuspecting commuters, and scrawling glasses and moustache on her face (poster face and actual face).

We imagine that Trivago cannot believe its luck with this ad campaign that's so middle-of-the-road, it has sent shivers down London's collective spine.

Just as Coldplay have ridden the winds of serendipity to become one of the bands of our generation, will this ad campaign join the great pantheon of advertisements alongside the Guinness horses and those Smash-guzzling robots? We bloody hope not.
